Noting a module change - I decided to return the Black Hole DSP 2 - Replacing it with a Mimeophon. I think the BHDSP does a lot of stuff, but I didn't think it did any of them that well. The max delay is too short for me (but it is great for phasing/flanging though) and the reverb didn't wow me either. And you can't sync it. I think I'll get along with Mimeophon better.

In addition to S&H, what else can I add for randomness/probability?

Cheers
